3.C. The computer generated 'H NMR predictions for compounds A through F are on the next pages. For each spectrum, perform the following tasks. 1) Draw the compound corresponding to the spectrum in the right margin. 2) Indicate at least two distinct signals on the spectrum that helped you identify the correct compound. Briefly explain why they are diagnostic to that one compound. i) Structure 2x Useful signals 3H 1H + 1H (broad singlet) 3H 1H 5H 1H Compound: A B C D E F O 6 5 2 3 PPM Structure ii) Useful signals 6H 3H I 2H 2H 2H 2H 1H Compound: B D EF 00 2 PPM Hii) Structure Useful signals 2 x 3H 3H 1H 1H 1H 1H 1 1 1 Compound: C D EF O A OO 7 6 5 3 2 PPM
